MY02 Wagon: New clutch...problems...need help

bwawuz · 11-15-2006, 01:07 AM

MY02 wagon

i just changed my clutch to a spec stage 2, and installed koni's/gc coilovers/mrt camber plates (in the garage with hand tools, it sucked). suspension feels solid. problem is when i let off the gas there is a sound developing into vibration in the rear end. sounds like the driveshaft might not be lined up i think, but i marked the driveshaft and rear diff with paint as per the subaru manual. did i miss something in aligning the driveshaft? as soon as i put the clutch in the sound ceases. it's more of a low tone more vibration at 40mph in 4th gear. i also jacked the rear end up by the rear diff and was wondering if that might have hurt it. i'd jacked up E30's at the rear diff before so i didn't think it would be a problem on the rex. also, when i get on it and shift at 6k rpms when i put the clutch in there is a slight slapping sound as if there's something loose in the drivetrain. Please help, sry if i sound like a newbie.

did you put a lightened flywheel in also per chance?

bwawuz · 11-15-2006, 01:12 PM

no sir. stock flywheel, new pilot bearing. fyi, spec stage 2 is definitely more grabby than stock, but not too bad, takes a lil different driving style.

after much reading it seems that the slapping/clunking sound might just be the normal subie rear subframe setup, am i wrong in that assumption?

You didn't hurt the car jacking it up by the rear end. That's for sure.

...when I first installed my new clutch I had the exact same problem. I didn't resurface my flywheel. I just tried to sand it as evenly as possible with an orbital sander. I think this caused the clutch to be too grabby at first and the car shook like hell when I would slowly release the clutch with no gas. The rear diff. shook the most. After about 200 miles it went away completely.
